Recently, successful attempts have been made to convert carbon monoxidand dioxid into valuable liquid organic compounds such as methanol andother oxygenated organic compounds, which latter for a great partconsist of isobutyl alcohol and other alcohols, or into liquidhydrocarbons or mixtures of both, the rocess of producing such compoundsconsi'stlng in reducing the oxids 1 of carbon by means of hydrogen orhydrocarbons at a high pressure and temperature and under the influenceof suitable catalysts.

The production of methanol is described for instance in the FrenchPatent 571,356.

We have now discovered that all the synthetic products aforementionedare'excellent motor fuels and, as they can be produced from any kind ofcoal, they are apt as substitutes for gasoline, where and when a shortae of the latter should exist and they ma a so be used to dilute theusual motor fue by mixin the latter with the aforementioned synt eticproducts or either of them.

Thesynthetic fuels mentioned which are obtained from carbon oxids bycatalytic reduction under increased pressure are characterized by theirregularly containing traces of iron carbonyl, for example between 50 and200 milligrammes per gallon which traces however do .not influence theuse of the products either advantageously or in a bad manner.

l The said thetic roducts may be used either direct y or be orehandsub'ected to any suitable treatment, for example purification orfractional distillation, or other treatment, such as for examplecatalytic hydrogenation. Diiferent products, for examplle syntheticmethanol or higher alcohols or ydrocarbons may'also be mixed with eachother.

and in Germany May 8,1923.

What we claim is 4 1. A motor fuel comprising a liquid product obtainedby the hydrogenation of a carbon oxid under high pressure by catalyticreduction and containing traces of an iron carbonyl.

-2. A motor fuel comprising a liquid product obtained by thehydrogenation of a carbon oxid under high pressure by catalyticreduction and containing traces of a metal carbonyl.

3.. Amotor fuel comprising a liquid product obtained by thehydrogenation of a carbon oxid under high pressure, which product ischaracterized by containing a trace of metal carbonyl.

4. As a composition of matter a motor fuel comprising a usual motor fuelmixed with a liquid fproduct obtained by the hydrogenation o a carbonoxid under high pressure containin a metal carbon 1.

5. A motor fuel mcludin an alip atic alcohol obtained by the hyrogenation of a carbon oxid under high pressure by catalytic reduction.

6. As a motor fuel a li uid product including the mixtures of a oxidunder high pressure by catalytic reduction. 7. As a motor fuel a liquidproduct including the mixtures of aliphatic alcohols obtainedby thehydrogenation of a carbon oxid under high ressure by catalyticreduction, mixed wit -a usual motor fuel.

In testimony whereof we hereunto aflix our signatures.
